<VV> Cylinder assemblies vs Pistons/rings + rebore

[moonpie8n at comcast.net]

  Larry's  Corvair  rebores  them  for  around  150$, which  is  cheap , ... considering  SET-UP  time. The  problem  is , ...... where  to  get  good  rings. GM  cylinders  were  supplied  with  chrome  rings  which  stand  up  very  well  to  the  heat  of  everyday  driving. Many  suppliers  only  stock  steel  or  cast  iron  rings  for  Corvair. Grant  rings  are  junk , ...... the  rest  are  really  hard  to  find [like  speed - pro / sealed  power  Kromex]. IF  cost  is  no  object, ... get  Total  seal , and  get  your  cylinders  bored, otherwise  just  get  a  set  of  cylinders  and  piston/rings  from  Clarks...... WE  made  the  most  power  [on  the  dyno]  with  cast  iron  rings , but , they  don't  last  long [One  Season - 14 - 16, ... 5 mile  heats  at  wide  open  throttle]

Subject: <VV> Cylinder assemblies vs Pistons/rings + rebore 

Perhaps this question is premature, since I haven't yet had the chance 
to take my engine apart (I need to use my limited Corvair time to repair 
my snowblower since we're having a ridiculous amount of snow in Boston 
this winter).... but does anyone on the list have insight as to the 
wisdom of buying new piston/cylinder assemblies from Clark's vs just 
getting oversized pistons/rings and having my existing cylinders 
rebored? It seems as though the difference in price for the parts is a 
few hundred dollars, but how much does reboring cost? 

Also, what of the "full fin" cylinders available from Clark's? Any thoughts? 

Thanks!
